repl: add :lh command

[Synthetica9]

:lh <hash> is a convenience shortcut, it does the same as
:l https://github.com/nixos/nixpkgs/archive/<hash>.tar.gz.

I'm not sure if this sort of thing is within scope, but it is something I would use very often myself, so I can imagine this would also be useful to other people.

It would probably be better to add flake support to the repl (#3803), e.g. a command like :lf <flakeref> would allow :lf nixpkgs/<hash>.

I agree, it was just that I saw this would be a pretty trivial change to make, so I wanted to have the option out there. Full flake support seems to be a significantly bigger undertaking.

Is there no easy to access function that loads flakes? There is a builtin builtin.getFlake - I would expect this one to be also reachable from c++.

Still a good feature request

We now have the :lf that @edolstra suggested (from #6233). Furthermore, one can also do :a fetch-however-one-likes. Can we close this?

[Ericson2314]

Closing per the above.
